Core-js is a modular standard library for JavaScript that polyfills ECMAScript features not implemented in older browsers. It provides a way to use the latest ECMAScript features across different environments by patching missing functionalities. Core-js includes polyfills for features like Promises, Symbols, Iterators, and more, ensuring consistent behavior and compatibility.

Compared to other polyfill libraries, Core-js offers a comprehensive set of polyfills and allows for selective inclusion of specific features to optimize bundle size. It is actively maintained and regularly updated to support new ECMAScript standards, making it a reliable choice for ensuring cross-browser compatibility in modern web development.
